LOOKING AT THE RISK MAPPING & REPORTING OF NETWORK LEAKS USING REMOTE SENSING
1. Dr. Moira Smith (D-CAT)
Dr. Quentin BECHET (Veolia)
Using trees as
sensors to predict
sewer blockages
2. WE ARE HELPING GREATER WESTERN WATER TO
OPTIMISE THEIR SEWER MAINTENANCE PROGRAM
Western Network length (20/21)
1,563 km
Western blockage rate (20/21)
15.3 blockages / 100km / year
Maintenance rate (20/21)
~5% / year
3. IDEALLY WE WANT DIRECT TECHNIQUES
TO TARGET WHAT PIPES TO CLEAN
Smart sewer lid Kando sensors
Examples of sensor technologies trialled
at Greater Western Water Sensor-based
technologies have
great potential but are
still very expensive!
The entire network
cannot be equipped
with these sensors,
especially in Australia
where networks are
extensive!
4. THE TREES CAN BE USED
AS BLOCKAGE SENSORS
In Victoria, the large majority of
blockages are caused by tree
roots
5. D-CAT DEVELOPED AN ALGORITHM FOR TREE GROWTH
INITIALLY FOR THE FORESTRY INDUSTRY
For deforestation For monitoring planting, growth & regeneration

16. CONCLUSIONS
& NEXT STEPS
Promising results
SkyCam Blockages was proven through multiple trials over years and different locations in
Victoria to reliably highlight anomalous trees near to sewer networks, providing utilities the
ability to optimise network inspections and cleaning.
Next steps
SkyCam Blockages will shortly (today!) go live at Greater Western Water.
